Quality rechargeable Fenix 18650 2300 mAh (ARB-L2M) batteries with protection (protected) are based on lithium-ion technology. Li-ion rechargeable batteries are characterised by very high capacity, do not suffer from memory effect and have no self-discharge. Li-ion in 18650 size are the best choice in terms of stored energy relative to the dimensions and weight of the battery.
Protection of Fenix batteries consists of internal safety mechanisms and protective electronics. Added electronic circuits prevent overcharging of the cell, excessive discharge and protect against short circuit or excessively high current draw.
If the battery electronics detect that limit values have been reached, they safely disconnect the cell. Internal protection consists of a separator, overheat protection (PTC thermal protection) and a special anti-explosion valve. If the gas pressure in the cell exceeds a certain threshold, the internal separator isolates the electrodes inside the battery and thereby effectively interrupts the exothermic reaction, and the anti-explosion valve releases excess gas pressure from the battery.
Thanks to the combination of electronic and mechanical (thermal and pressure) protection, Fenix batteries are among the safest available Li-ion batteries.
In size, the 18650 battery corresponds roughly to two CR123A lithium batteries, which is why it is often used in torches as a rechargeable alternative to these primary cells. Check first whether your device supports this cell.
This battery is designed for use in, for example, Fenix LED torches LD75C, Fenix SD10, Fenix SD11, Fenix SD20, Fenix FD30, Fenix FD41, Fenix E35, Fenix PD32, Fenix PD35, Fenix TK09, Fenix TK15, Fenix TK16, Fenix TK25, Fenix TK32, Fenix TK35, Fenix TK47, Fenix TK75, Fenix TK76. LED head torches Fenix HL55, Fenix HL60R, Fenix HP25R, Fenix HP30R and bicycle lights Fenix BC21R and Fenix BC30. Note that due to the length of 70 mm and diameter, it may not fit into some older models – for example Fenix PD31, TK11, TK21, TK30.

Warning

• If you are using an older charger purchased around 2014 or earlier, first check whether batteries with a length of 69–70 mm will fit into it.
• If possible, do not discharge the battery below 2.5 V
• Do not short-circuit the battery (do not connect the cell terminals with a conductor)
• Do not throw the battery into fire or water
• Never insert the battery into the charger in reverse (with opposite polarity)
• When using the battery, observe safety guidelines
• Use only an appropriate charger that supports Li-ion batteries
